Description

Noninvasive ventilator prevents pressing sore face protection device

Technical Field

The utility model relates to a decompression pad of a respirator mask, in particular to a pressure sore prevention face protection device of a noninvasive respirator.

Background

Breathing apparatus assisted ventilation can promote gas exchange and oxygenation, improve dyspnea symptoms, and has been widely used in respiratory disorder diseases caused by various reasons. However, when the respirator is in use, the mask can continuously press the nose and face and forehead of a patient, and pressure sores are easily caused. If the patient using the ventilator is elderly, the skin will be loose, the nutritional status will be relatively poor and the risk of pressure sores will be higher. Pressure sores not only can cause nose and face skin infection, but also can influence the treatment compliance of the noninvasive breathing machine of patients, and are not beneficial to the control of diseases. There are two main types of respiratory machine related pressure sore prevention measures commonly used in clinic at present, one is for each type of respiratory machine mask. First, soft materials are used for both the oral-nasal mask and the full face mask. The mask is proper in tightness, preferably 1-2 fingers are accommodated, facial pressure sores caused by over tightening of the fixing belt are avoided, and the mask is loosened once in 3-4 hours. The method is dependent on the illness state of the patient, and pressure sores still occur when the patient has serious illness state and can not relax the mask in time.

The other method is to protect the face skin, and the skin can be coated with vaseline and other protective dressings. The dressing used in clinic at present mainly comprises hydrocolloid dressing, O-shaped gauze, face pressure reducing pad and foam dressing. (1) Hydrocolloid dressing advantages: the upper layer contains transparent materials composed of urethane, and has the advantages of observing skin state at any time, forming a closed environment by attaching the skin-care mask to the face, isolating bacteria and preventing infection. Moreover, the adhesive is good, the fixing is easy, and the main defects are that the pressure points are easy to miss and cause pressure sores because the pressure points need to be cut according to the face stress points of the patient. (2) O-gauze advantage: the O-shaped gauze is attached to the face, so that the air leakage phenomenon of the breathing machine can be improved. Disadvantages: the gauze material is slightly rough, and is easy to rub to cause skin damage. (3) Facial decompression pad advantage: through pasting the decompression pad, set up behind the face of two extension strips laminating breathing machine face mask contact respectively on the bridge of the nose, communicate with each other with the bridge of the nose and be located under the nose cup for keep apart between nose cup and the patient face has one deck protection pad, avoids pressing the sore to take place, shortcoming: the pasting fastness of decompression pad is not good, when the breathing machine face guard of refastening, can cause taking place the skew between breathing machine face guard and the decompression pad, reduces the effect of protection. (4) Foam dressing advantages: the foam dressing is a novel soft silicone adhesive technology series foam dressing, can reduce tissue friction force and shearing force, keep good skin humidity and relatively anaerobic environment, and promote damaged tissue regeneration and wound repair. The foam dressing has self-adhesive property, is firmly adhered, can be repeatedly used, and has good effect on facial pressure sores caused by the noninvasive ventilator. Disadvantages: the foam dressing material is thicker, makes breathing machine face guard and facial laminating nature poor, appears breathing machine gas leakage easily, and foam dressing is mostly flesh color, need tear the dressing when observing skin, and is very inconvenient.

Compared with the artificial airway lower respiratory machine, the noninvasive respiratory machine has the characteristics of noninvasive property, less complications, simple operation flow and the like, and is widely applied clinically. For the patient needing emergency intubation, the ventilation of the respirator mask is used for pre-oxygenation, so that the oxygen storage of the patient can be obviously improved, and the safety time limit of the tracheal intubation can be prolonged. However, when the noninvasive ventilator is applied, the mask is required to be fastened on the mouth and nose of a patient, so that the skin of the face is continuously pressed, and meanwhile, the silica gel mask is poor in air permeability, so that the skin of the patient is easily damaged. Studies show that the incidence rate of facial pressure sores can reach 27% in patients treated by non-invasive positive pressure ventilation clinically. And the patient using the noninvasive ventilator for assisting ventilation often has chronic basic diseases, and is accompanied by pulmonary hypertension and right heart failure, so that facial edema is easy to cause, and the risk of pressure sores is increased.

The utility model relates to a noninvasive respirator mask protection device which is based on various factors of pressure sore occurrence in clinic at present,
